The P - V diagram of a diatomic ideal gas system going under cyclic process as shown in figure. The work done during an adiabatic process C D is (use γ = 1 . 4 ) :
Options
- A– 500 J
- B– 400 J
- C400 J
- D200 J
Correct answer
A. – 500 J
Step-by-step solution
Adiabatic process is from C to D W D = P 2 V 2 - P 1 V 1 1 - γ = P D V D - P C V C 1 - γ = 200 ( 3 ) - ( 100 ) ( 4 ) 1 - 1 . 4 = - 500 J
